Answer:
-816.8 ft²/min
Step-by-step explanation:
The rate of change of area is the product of the rate of change of radius and the circumference of the circle. At the time of interest, ...
dA/dt = C·dr/dt = 2πr·dr/dt
dA/dt = 2π·(26 ft)(-5 ft/min)
dA/dt = -260π ft²/min ≈ -816.8 ft²/min
Answer:
The answer is: y = - |x+1|+1
No, since the slopes are different
for 1 line
y = 4x - 4
slope = 4
for 2 line
4y = 24x - 96
slope = 24/4 = 6
